Letters Patent No. 93,039, dated July 27, 1869.

'mrnovnmnnr m TOOL non romvnnc-i arcs on THE rmcxs or B TTL S.

The Schedule referred to in these Letters Patent and making part of thesame.

To whom it may concern Be it known that I, THOMAS BARRETT, ofCharlestown, in the county of Middlesex, and State of Massachusetts,.have invented a new and'useful Machine or Tool for Forming Lips on thevNecks of Bottles, when the neck is shaped; and I do hereby declare thatthe following is a'fnll, clear, and exact description of theconstruction and operation of the same, reference'being made to theannexed drawings, making part of this specification, in which Figure 1is a side elevation;

' Figure 2, an edge elevation;- and Figure 3, a side sectionalelevation, exhibiting the tool when used.

In fig. 1 is shown a general view of the tool when open and ready foruse, in which-- i A is a conical plug, to be inserted in the neck of thebottle to be shaped.

B and O are dies for shaping the exterior of the neck.

D and E are the handles.

F is a rod, to which plug A is secured, and which passes through thespring-bow M, and is there secured and adjusted by the screw and nuts,as shown.

G is the lip-forming lever pivoted on the guide-stem K. The upper end isbent and passes through handle D. The lower or lip-forming end H, passesthrough shoulder N, on plug A, and is held in the recess J in the plugA, by means of spring 0.

In die B is recess 1, which is made of the shapeof the lip to be formed.I

K K are guide-stems which encircle rod 1:, and pass throughhandleslD andE, and are used to preserve the plug in a central position.

The manner of forming lips on bottles heretofore and now, has been, andis to first shape the neck by a tool similar to the one shown, and,after removing the tool, to inserta rod in the neck, and pull theflexible glass or ware to one side, into a rudely shaped lip.

In so doing, the neck is always more or less misshapen; the hole in theneck is also distorted. To remedy this, the tool is again applied torestore the shape, which cannot be well done because of the presence ofthe lip.

In the tool which I have invented, and here shown, a symmetrical neckand perfectly formed lip are invariably secured, by reason of the factthat the tool has notto be withdrawn, and that the neck is within thetool while the lip is formed.

In operation, the tool is held in the right hand; the bottle to beshaped is suitably held, and rotated by the left. When plug A isinserted in the bottle, the dies B and G are gradually brought together,while the bottle revolves, till they come in contact with shoulder N.

The neck is now formed, and the revolving ceases.

The operator now presses his forefinger on the upper end of the leverGr, forcing it into the position shown in fig. 3, by which means H hasbeen forced out of recess J, driving before it the pliant glass 01' wareinto the lip-forming recess I.

This completes the operation of shaping the neck and forming the lip.The tool is now removed, and the bottle is finished.

That I claim as my invention, and for which I desire Letters Patent,is-- 1. The combination of a neck-shaping and lip-forming tool,substantially as shown.

2. The retractile lip-former and lip-forming recess in the die,substantially as shown, and'for the purpose set forth.
